The only downside to Amy Ryan being on The Office is that I don't think she's a permanent addition to the cast. That means her sweet-natured friendship/burgeoning relationship with Michael Scott will eventually come to a quick, and possibly sad, end.

As awkward as it might have been for the Dunder-Mifflin staff to sit through their musical number ("Let's Get Ethical," to the tune of Olivia Newton John's "Physical"), I actually found it quite charming, in a dorky sort of way.

We learned a lot about Ryan's Holly in this episode. She's got the same goofy sense of humor as Michael (notice she was willing to crack the same Terminator jokes as he was even as they talked about what should happen with Meredith), but she's still takes her job seriously enough to know that there are some things that probably shouldn't be kept quiet.

And although it might seem to her that her seriousness is what caused the brief rift between her and Michael, I'd guess it was because he was hurt to learn that she doesn't share his belief that the workplace is like a family. Great work by Steve Carrell in this episode, especially in the scene toward the end, after he hears Holly get dressed-down by the main office in the same way he'd been many, many times before. (He says he wants to say "I told you so," but instead comes to her rescue.)

Other stuff I liked:

Jim trying to goad Dwight into committing more "time theft" by maligning Battlestar Galactica. Seeing as how he knew just what to get wrong ("Dumbledore Calrissian"), he's either absorbed all this stuff from Dwight, or is secretly a sci-fi fan.

The debate over "stealing bread to feed your family."

Michael's confession in the ethics seminar: "When I first discovered YouTube, I did not work for five days."

Ryan admitting that defrauding the company was a huge rush. Hey, it meant he got to hook up with a woman who looked like someone who was on Survivor (the writers of the Office love referencing that show, possibly because it airs the same night).
